OMG IS THIS THE ACTUAL G TEWANIIIII THE AUTHOR OF CENGAGE
19:00 formula for n squares selection but not in same column or row
And m*m chessboard
(m²+(m-1)²+........(m-n)²)/n!
16:30, 19:45 Multiple counting then divide by n! (n = no. of the item selected).
combinations are always selected simultaneously not one by one so, we remove the arrangements from it ........
Sir your lectures are indeed a boon. Coaching classes only prepare for JEE Main , best tutoring for JEE Advanced
Hello senior..are you in IIT now ?
Beautiful Content sir. Such a lucid way of explaining tough concepts.
Amazing!!
In cengage algebra there is less problem based on this type plz add it would be helpful for us
Glad that he used cell address such b2, g5 etc instead of coordinate system by other teachers,like it as a chess player
You r the greatest teacher for iit sir, i m also a maths teacher and i want to be like you..
Idk
Eh
Sir
Question is that there are 16 companies which needs to be arranged in a chess board where not more than two companies can be arranged in a row ,not more than two companies can be arranged in a column and not more than two companies can be arranged in diagonals.U need to find the number of ways these 16 companies can be arranged on the chess board fulfiling the above conditions.
U have explained this concept so easily ❤
Use more english words sir it will be better to understood for south indians also 😊
understand*
Just learn Hindi dude
@@kshitijsingh9687 Just speak english bruv
Bhai english me bhi lecture available hn wo dekhlo
Last question me *2 or Hona chayiye dusre opposite corners se bhi to Ja sakte h...question me corner to other diagonally opposite corner h..
Sir Cant we select squares with side 3 units and multiply it by 2 to get the answer of the no of squares with common diagonal in 3rd prob
Sir in 2nd question : Acording to question '2 small squares should not be in same row or same column' but you should it such that are not in same row and same column.
Yes I thought about that first . I am in class 9
@@susheelchabra4752 this is not a chess class nor a English class; "kid"!
Word "Or" is correct.
Why not "and"?
Ans. If you select let's say e4 square, then the second square can be either in same row or in same column.
A square cannot be in same column and same row at same time (until and unless you select same square again).
@@thegrandmaster7549 even if it's neither chess class nor English class, wordings and it's meanings makes a lot of difference.
As a mathematics teacher and researcher I want to advise you, instead of looking towards subjects seperately, look them together for learning and making world perfect out of it.
Beautifully explained ❤
Sir aaplog kitne achhe ho ...Kuch na kuch time hm students ke liye nikal h lete ho
The last question was way too interest provoking dude❤️💗💗❤️
Two select two on a column will be 8 ways it’s beyond understanding time 28:00 minutes

Superb sir g
Sir yur special effects for writing is different,
Do u use a glass as a board in between camera n u if yes then do u practice writing in opposite way like how in mirror image from mirror or some other special effect.
I was thinking about this from a long time. The answer is simple. There is a glass layer in between camera and sir. Sir writes normally using *right hand* and then final video is left-right inverted.
Thankyou so much sir
